Vespa Cosa 200 GS coldstart 

azwris Thanks! The Vespa Cosa has a SIP Road exhaust and associated carburetor adjustments. The mileage is around 21,000 kilometers (13,000 miles).

@@Klijndijk02 Thank you. I am still thinking if I should put the original one, this one or the equivalent of Poliini.

@@azwris I will install the SIP road exhaust if I were you, however you have to look at the carburettor settings.

@@Klijndijk02 I still like the sound of the original NOS exhaust better though..plus I won't have to make changes on my carb as it is quite old and not easy to be tuned. Thank you very much for the response!

@@azwris I will look at the carburettor setting anyway, because the engine with original carburettor setting and exhaust has a high risk of overheating.

Vespa Daniele 1L = 21.77km average (my own calculation at Spritmonitor)

I sold it last year for around €1000,- ($1191,- current course).
